Bean variety sv3902ga

ABSTRACT

The invention provides seed and plants of the bean line designated SV3902GA. The invention thus relates to the plants, seeds and tissue cultures of bean line SV3902GA, and to methods for producing a bean plant produced by crossing a plant of bean line SV3902GA with itself or with another bean plant, such as a plant of another line. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of a plant of bean line SV3902GA, including the pods and gametes of such plants.

FIELD OF THE INVENTION

The present invention relates to the field of plant breeding and, morespecifically, to the development of bean line SV3902GA.

BACKGROUND OF THE INVENTION

The goal of crop breeding is to combine various desirable traits in asingle variety/hybrid. Such desirable traits may include greater yield,resistance to insects or pests, tolerance to heat and drought, betteragronomic quality, higher nutritional value, growth rate and fruit orpod properties.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: a plant self-pollinates ifpollen from one flower is transferred to the same or another flower ofthe same plant or plant variety. A plant cross-pollinates if pollencomes to it from a flower of a different plant variety.

Plants that have been self-pollinated and selected for type over manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny, a homozygous plant. A crossbetween two such homozygous plants of different varieties produces auniform population of hybrid plants that are heterozygous for many geneloci. Conversely, a cross of two plants each heterozygous at a number ofloci produces a population of hybrid plants that differ genetically andare not uniform. The resulting non-uniformity makes performanceunpredictable.

The development of uniform varieties requires the development ofhomozygous inbred plants, the crossing of these inbred plants, and theevaluation of the crosses. Pedigree breeding and recurrent selection areexamples of breeding methods that have been used to develop inbredplants from breeding populations. Those breeding methods combine thegenetic backgrounds from two or more plants or various other broad-basedsources into breeding pools from which new lines are developed byselfing and selection of desired phenotypes. The new lines are evaluatedto determine which of those have commercial potential.

One crop species which has been subject to such breeding programs and isof particular value is garden bean (Phaseolus vulgaris (snap)). Beansare annual, warm-season legumes. Garden beans, also known as greenbeans, snap beans, or pole beans, are grown primarily for their pods,which are harvested for consumption in their succulent form, whereas drybeans (Phaseolus vulgaris (dry)), lima beans (Phaseolus limensis), andsoybeans (Glycine max) are usually grown for the seed itself. Inaddition, the bean leaf is occasionally used as a leaf vegetable, andthe straw is used for fodder.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides a bean plant of the beanline designated SV3902GA. Also provided are bean plants having all thephysiological and morphological characteristics of bean line SV3902GA.Parts of the bean plant of the present invention are also provided, forexample, including pollen, an ovule, a pod, and a cell of the plant.

The invention also concerns seed of bean line SV3902GA. The bean seed ofthe invention may be provided as an essentially homogeneous populationof bean seed of the line designated SV3902GA. Essentially homogeneouspopulations of seed are generally free from substantial numbers of otherseed. Therefore, in one embodiment, seed of line SV3902GA may be definedas forming at least about 97% of the total seed, including at leastabout 98%, 99%, or more of the seed. The population of bean seed may beparticularly defined as being essentially free from hybrid seed. Theseed population may be separately grown to provide an essentiallyhomogeneous population of bean plants designated SV3902GA.

In another aspect of the invention, a plant of bean line SV3902GAcomprising an added heritable trait is provided. The heritable trait maycomprise a genetic locus that is, for example, a dominant or recessiveallele. In one embodiment of the invention, a plant of bean lineSV3902GA is defined as comprising a single locus conversion. In specificembodiments of the invention, an added genetic locus confers one or moretraits such as, for example, herbicide tolerance, insect resistance,disease resistance, and modified carbohydrate metabolism. In furtherembodiments, the trait may be conferred by a naturally occurring geneintroduced into the genome of the line by backcrossing, a natural orinduced mutation, or a transgene introduced through genetictransformation techniques into the plant or a progenitor of any previousgeneration thereof. When introduced through transformation, a geneticlocus may comprise one or more genes integrated at a single chromosomallocation.

In another aspect of the invention, a tissue culture of regenerablecells of a plant of line SV3902GA is provided. The tissue culture willpreferably be capable of regenerating plants capable of expressing allof the physiological and morphological characteristics of the line, andof regenerating plants having substantially the same genotype as otherplants of the line. Examples of some of the physiological andmorphological characteristics of the line SV3902GA include those traitsset forth in the tables herein. The regenerable cells in such tissuecultures may be derived, for example, from embryos, meristems,cotyledons, pollen, leaves, anthers, roots, root tips, pistil, flower,seed and stalks. Still further, the present invention provides beanplants regenerated from a tissue culture of the invention, the plantshaving all the physiological and morphological characteristics of lineSV3902GA.

In yet another aspect of the invention, processes are provided forproducing bean seeds, plants and pods, which processes generallycomprise crossing a first parent bean plant with a second parent beanplant, wherein at least one of the first or second parent bean plants isa plant of the line designated SV3902GA. These processes may be furtherexemplified as processes for preparing hybrid bean seed or plants,wherein a first bean plant is crossed with a second bean plant of adifferent, distinct line to provide a hybrid that has, as one of itsparents, the bean plant line SV3902GA. In these processes, crossing willresult in the production of seed. The seed production occurs regardlessof whether the seed is collected or not.

In one embodiment of the invention, the first step in “crossing”comprises planting seeds of a first and second parent bean plant, oftenin proximity so that pollination will occur for example, mediated byinsect vectors. Alternatively, pollen can be transferred manually. Wherethe plant is self-pollinated, pollination may occur without the need fordirect human intervention other than plant cultivation.

A second step may comprise cultivating or growing the seeds of first andsecond parent bean plants into plants that bear flowers. A third stepmay comprise preventing self-pollination of the plants, such as byemasculating the male portions of flowers, (i.e., treating ormanipulating the flowers to produce an emasculated parent bean plant).

A fourth step for a hybrid cross may comprise cross-pollination betweenthe first and second parent bean plants. Yet another step comprisesharvesting the seeds from at least one of the parent bean plants. Theharvested seed can be grown to produce a bean plant or hybrid beanplant.

The present invention also provides the bean seeds and plants producedby a process that comprises crossing a first parent bean plant with asecond parent bean plant, wherein at least one of the first or secondparent bean plants is a plant of the line designated SV3902GA. In oneembodiment of the invention, bean seed and plants produced by theprocess are first generation (F₁) hybrid bean seed and plants producedby crossing a plant in accordance with the invention with another,distinct plant. The present invention further contemplates plant partsof such an F₁ hybrid bean plant, and methods of use thereof. Therefore,certain exemplary embodiments of the invention provide an F₁ hybrid beanplant and seed thereof.

In still yet another aspect of the invention, the genetic complement ofthe bean plant line designated SV3902GA is provided. The phrase “geneticcomplement” is used to refer to the aggregate of nucleotide sequences,the expression of which sequences defines the phenotype of, in thepresent case, a bean plant, or a cell or tissue of that plant. A geneticcomplement thus represents the genetic makeup of a cell, tissue orplant, and a hybrid genetic complement represents the genetic make up ofa hybrid cell, tissue or plant. The invention thus provides bean plantcells that have a genetic complement in accordance with the bean plantcells disclosed herein, and plants, seeds and plants containing suchcells.

Plant genetic complements may be assessed by genetic marker profiles,and by the expression of phenotypic traits that are characteristic ofthe expression of the genetic complement, e.g., isozyme typing profiles.It is understood that line SV3902GA could be identified by any of themany well known techniques such as, for example, Simple Sequence LengthPolymorphisms (SSLPs) (Williams et al., Nucleic Acids Res., 18:6531-6535, 1990), Randomly Amplified Polymorphic DNAs (RAPDs), DNAAmplification Fingerprinting (DAF), Sequence Characterized AmplifiedRegions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR),Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858,specifically incorporated herein by reference in its entirety), andSingle Nucleotide Polymorphisms (SNPs) (Wang et al., Science,280:1077-1082, 1998).

In still yet another aspect, the present invention provides hybridgenetic complements, as represented by bean plant cells, tissues,plants, and seeds, formed by the combination of a haploid geneticcomplement of a bean plant of the invention with a haploid geneticcomplement of a second bean plant, preferably, another, distinct beanplant. In another aspect, the present invention provides a bean plantregenerated from a tissue culture that comprises a hybrid geneticcomplement of this invention.

In still yet another aspect, the invention provides a plant of an inbredbean line that exhibits a combination of traits including good yield,medium-late maturity, small pod diameter and dark green and glossy podcolor. In certain embodiments, the trait may be defined as controlled bygenetic means for the expression of the trait found in bean lineSV3902GA.

In still yet another aspect, the invention provides a method ofdetermining the genotype of a plant of bean line SV3902GA comprisingdetecting in the genome of the plant at least a first polymorphism. Themethod may, in certain embodiments, comprise detecting a plurality ofpolymorphisms in the genome of the plant. The method may furthercomprise storing the results of the step of detecting the plurality ofpolymorphisms on a computer readable medium. The invention furtherprovides a computer readable medium produced by such a method.

In still yet another aspect, the present invention provides a method ofproducing a plant derived from line SV3902GA, the method comprising thesteps of: (a) preparing a progeny plant derived from line SV3902GA,wherein said preparing comprises crossing a plant of the line SV3902GAwith a second plant; and (b) crossing the progeny plant with itself or asecond plant to produce a seed of a progeny plant of a subsequentgeneration. In further embodiments, the method may additionallycomprise: (c) growing a progeny plant of a subsequent generation fromsaid seed of a progeny plant of a subsequent generation and crossing theprogeny plant of a subsequent generation with itself or a second plant;and repeating the steps for an additional 3-10 generations to produce aplant derived from line SV3902GA. The plant derived from line SV3902GAmay be an inbred line, and the aforementioned repeated crossing stepsmay be defined as comprising sufficient inbreeding to produce the inbredline. In the method, it may be desirable to select particular plantsresulting from step (c) for continued crossing according to steps (b)and (c). By selecting plants having one or more desirable traits, aplant derived from line SV3902GA is obtained which possesses some of thedesirable traits of the line as well as potentially other selectedtraits.

In certain embodiments, the present invention provides a method ofproducing beans comprising: (a) obtaining a plant of bean line SV3902GA,wherein the plant has been cultivated to maturity, and (b) collectingbeans from the plant.

These and other features and advantages of this invention are describedin, or are apparent from, the following detailed description of variousexemplary embodiments of the devices and methods according to thisinvention.

B. Breeding Bean Line SV3902GA

One aspect of the current invention concerns methods for crossing thebean line SV3902GA with itself or a second plant and the seeds andplants produced by such methods. These methods can be used forpropagation of line SV3902GA, or can be used to produce hybrid beanseeds and the plants grown therefrom. Hybrid seeds are produced bycrossing line SV3902GA with second bean parent line.

The development of new varieties using one or more starting varieties iswell known in the art. In accordance with the invention, novel varietiesmay be created by crossing line SV3902GA followed by multiplegenerations of breeding according to such well known methods. Newvarieties may be created by crossing with any second plant. In selectingsuch a second plant to cross for the purpose of developing novel lines,it may be desired to choose those plants which either themselves exhibitone or more selected desirable characteristics or which exhibit thedesired characteristic(s) in progeny. Once initial crosses have beenmade, inbreeding and selection take place to produce new varieties. Fordevelopment of a uniform line, often five or more generations of selfingand selection are involved.

Uniform lines of new varieties may also be developed by way ofdouble-haploids. This technique allows the creation of true breedinglines without the need for multiple generations of selfing andselection. In this manner, true breeding lines can be produced in aslittle as one generation. Haploid embryos may be produced frommicrospores, pollen, anther cultures, or ovary cultures. The haploidembryos may then be doubled autonomously, or by chemical treatments(e.g. colchicine treatment). Alternatively, haploid embryos may be growninto haploid plants and treated to induce chromosome doubling. In eithercase, fertile homozygous plants are obtained. In accordance with theinvention, any of such techniques may be used in connection with lineSV3902GA and progeny thereof to achieve a homozygous line.

New varieties may be created, for example, by crossing line SV3902GAwith any second plant and selection of progeny in various generationsand/or by doubled haploid technology. In choosing a second plant tocross for the purpose of developing novel lines, it may be desired tochoose those plants which either themselves exhibit one or more selecteddesirable characteristics or which exhibit the desired characteristic(s)in progeny. After one or more lines are crossed, true-breeding lines maybe developed.

Backcrossing can also be used to improve an inbred plant. Backcrossingtransfers a specific desirable trait from one inbred or non-inbredsource to an inbred that lacks that trait. This can be accomplished, forexample, by first crossing a superior inbred (A) (recurrent parent) to adonor inbred (non-recurrent parent), which carries the appropriate locusor loci for the trait in question. The progeny of this cross are thenmated back to the superior recurrent parent (A) followed by selection inthe resultant progeny for the desired trait to be transferred from thenon-recurrent parent. After five or more backcross generations withselection for the desired trait, the progeny are heterozygous for locicontrolling the characteristic being transferred, but are like thesuperior parent for most or almost all other loci. The last backcrossgeneration would be selfed to give pure breeding progeny for the traitbeing transferred.

The line of the present invention is particularly well suited for thedevelopment of new lines based on the elite nature of the geneticbackground of the line. In selecting a second plant to cross withSV3902GA for the purpose of developing novel bean lines, it willtypically be preferred to choose those plants which either themselvesexhibit one or more selected desirable characteristics or which exhibitthe desired characteristic(s) when in hybrid combination. Examples ofdesirable characteristics may include, for example, seed yield, seedsize, seed shape, seed uniformity, pod size, pod shape, pod color, poduniformity, early maturity, disease resistance, herbicide tolerance,seedling vigor, adaptability for soil conditions, adaptability forclimate conditions, and uniform plant height.

C. Performance Characteristics

As described above, line SV3902GA exhibits desirable performance traits.The results of an analysis of such traits are presented in Table 2 belowand in FIGS. 1-3. For example, when compared with Star 2052 andPaulista, SV3902GA has better yield (FIG. 1) and disease resistance.SV3902GA also has a lower percentage of pods above 10.5 mm average (FIG.2), and a very good pod length (similar to Paulista) that packs easilyinto pannets (FIG. 3). SV3902GA pods are of high quality and attractive,with a good shelf life.

D. Further Embodiments of the Invention

In certain aspects of the invention, plants described herein areprovided modified to include at least a first desired heritable trait.Such plants may, in one embodiment, be developed by a plant breedingtechnique called backcrossing, wherein essentially all of themorphological and physiological characteristics of a variety arerecovered in addition to a genetic locus transferred into the plant viathe backcrossing technique. The term single locus converted plant asused herein refers to those bean plants which are developed by a plantbreeding technique called backcrossing, wherein essentially all of thedesired morphological and physiological characteristics of a variety arerecovered in addition to the single locus transferred into the varietyvia the backcrossing technique.

Backcrossing methods can be used with the present invention to improveor introduce a characteristic into the present variety. The parentalbean plant which contributes the locus for the desired characteristic istermed the nonrecurrent or donor parent. This terminology refers to thefact that the nonrecurrent parent is used one time in the backcrossprotocol and therefore does not recur. The parental bean plant to whichthe locus or loci from the nonrecurrent parent are transferred is knownas the recurrent parent as it is used for several rounds in thebackcrossing protocol.

In a typical backcross protocol, the original variety of interest(recurrent parent) is crossed to a second variety (nonrecurrent parent)that carries the single locus of interest to be transferred. Theresulting progeny from this cross are then crossed again to therecurrent parent and the process is repeated until a bean plant isobtained wherein essentially all of the desired morphological andphysiological characteristics of the recurrent parent are recovered inthe converted plant, in addition to the single transferred locus fromthe nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single locus of the recurrent variety ismodified or substituted with the desired locus from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphologicalconstitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross; one ofthe major purposes is to add some commercially desirable trait to theplant. The exact backcrossing protocol will depend on the characteristicor trait being altered and the genetic distance between the recurrentand nonrecurrent parents. Although backcrossing methods are simplifiedwhen the characteristic being transferred is a dominant allele, arecessive allele may also be transferred. In this instance it may benecessary to introduce a test of the progeny to determine if the desiredcharacteristic has been successfully transferred.

In one embodiment, progeny bean plants of a backcross in which SV3902GAis the recurrent parent comprise (i) the desired trait from thenon-recurrent parent and (ii) all of the physiological and morphologicalcharacteristics of bean line SV3902GA as determined at the 5%significance level when grown in the same environmental conditions.

Bean varieties can also be developed from more than two parents. Thetechnique, known as modified backcrossing, uses different recurrentparents during the backcrossing. Modified backcrossing may be used toreplace the original recurrent parent with a variety having certain moredesirable characteristics or multiple parents may be used to obtaindifferent desirable characteristics from each.

With the development of molecular markers associated with particulartraits, it is possible to add additional traits into an established germline, such as represented here, with the end result being substantiallythe same base germplasm with the addition of a new trait or traits.Molecular breeding, as described in Moose and Mumm, 2008 (PlantPhysiology, 147: 969-977), for example, and elsewhere, provides amechanism for integrating single or multiple traits or QTL into an eliteline. This molecular breeding-facilitated movement of a trait or traitsinto an elite line may encompass incorporation of a particular genomicfragment associated with a particular trait of interest into the eliteline by the mechanism of identification of the integrated genomicfragment with the use of flanking or associated marker assays. In theembodiment represented here, one, two, three or four genomic loci, forexample, may be integrated into an elite line via this methodology. Whenthis elite line containing the additional loci is further crossed withanother parental elite line to produce hybrid offspring, it is possibleto then incorporate at least eight separate additional loci into thehybrid. These additional loci may confer, for example, such traits as adisease resistance or a fruit quality trait. In one embodiment, eachlocus may confer a separate trait. In another embodiment, loci may needto be homozygous and exist in each parent line to confer a trait in thehybrid. In yet another embodiment, multiple loci may be combined toconfer a single robust phenotype of a desired trait.

Many single locus traits have been identified that are not regularlyselected for in the development of a new inbred but that can be improvedby backcrossing techniques. Single locus traits may or may not betransgenic; examples of these traits include, but are not limited to,male sterility, herbicide resistance, resistance to bacterial, fungal,or viral disease, insect resistance, restoration of male fertility,modified fatty acid or carbohydrate metabolism, and enhanced nutritionalquality. These comprise genes generally inherited through the nucleus.

Direct selection may be applied where the single locus acts as adominant trait. An example of a dominant trait is the anthracnoseresistance trait. For this selection process, the progeny of the initialcross are sprayed with anthracnose spores prior to the backcrossing. Thespraying eliminates any plants which do not have the desired anthracnoseresistance characteristic, and only those plants which have theanthracnose resistance gene are used in the subsequent backcross. Thisprocess is then repeated for all additional backcross generations.

Selection of bean plants for breeding is not necessarily dependent onthe phenotype of a plant and instead can be based on geneticinvestigations. For example, one can utilize a suitable genetic markerwhich is closely genetically linked to a trait of interest. One of thesemarkers can be used to identify the presence or absence of a trait inthe offspring of a particular cross, and can be used in selection ofprogeny for continued breeding. This technique is commonly referred toas marker assisted selection. Any other type of genetic marker or otherassay which is able to identify the relative presence or absence of atrait of interest in a plant can also be useful for breeding purposes.Procedures for marker assisted selection applicable to the breeding ofbean are well known in the art. Such methods will be of particularutility in the case of recessive traits and variable phenotypes, orwhere conventional assays may be more expensive, time consuming orotherwise disadvantageous. Types of genetic markers which could be usedin accordance with the invention include, but are not necessarilylimited to, Simple Sequence Length Polymorphisms (SSLPs) (Williams etal., Nucleic Acids Res., 1 8:6531-6535, 1990), Randomly AmplifiedPolymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF),Sequence Characterized Amplified Regions (SCARs), Arbitrary PrimedPolymerase Chain Reaction (AP-PCR), Amplified Fragment LengthPolymorphisms (AFLPs) (EP 534 858, specifically incorporated herein byreference in its entirety), and Single Nucleotide Polymorphisms (SNPs)(Wang et al., Science, 280:1077-1082, 1998).

E. Plants Derived From Bean Line SV3902GA by Genetic Engineering

Many useful traits that can be introduced by backcrossing, as well asdirectly into a plant, are those which are introduced by genetictransformation techniques. Genetic transformation may therefore be usedto insert a selected transgene into the bean line of the invention ormay, alternatively, be used for the preparation of transgenes which canbe introduced by backcrossing. Methods for the transformation of plants,including bean, are well known to those of skill in the art. Techniqueswhich may be employed for the genetic transformation of bean include,but are not limited to, electroporation, microprojectile bombardment,Agrobacterium-mediated transformation and direct DNA uptake byprotoplasts.

As is well known in the art, tissue culture of bean can be used for thein vitro regeneration of a bean plant. Tissue culture of various tissuesof beans and regeneration of plants there from is well known. Forexample, reference may be had to McClean and Grafton (Plant Sci.,60:117-122, 1989); Mergeai and Baudoin (B.I.C. Invit. Papers,33:115-116, 1990); Vanderwesthuizen and Groenewald (S. Afr. J. Bot.,56:271-273, 1990); Benedicic et al. (Plant Cell Tissue Org. Cult.,24:199-206, 1990); Malik and Saxena (Planta, 184(1):148-150, 1991).

To effect transformation by electroporation, one may employ eitherfriable tissues, such as a suspension culture of cells or embryogeniccallus or alternatively one may transform immature embryos or otherorganized tissue directly. In this technique, one would partiallydegrade the cell walls of the chosen cells by exposing them topectin-degrading enzymes (pectolyases) or mechanically wound tissues ina controlled manner.

A particularly efficient method for delivering transforming DNA segmentsto plant cells is microprojectile bombardment. In this method, particlesare coated with nucleic acids and delivered into cells by a propellingforce. Exemplary particles include those comprised of tungsten,platinum, and preferably, gold. For the bombardment, cells in suspensionare concentrated on filters or solid culture medium. Alternatively,immature embryos or other target cells may be arranged on solid culturemedium. The cells to be bombarded are positioned at an appropriatedistance below the macroprojectile stopping plate.

An illustrative embodiment of a method for delivering DNA into plantcells by acceleration is the Biolistics Particle Delivery System, whichcan be used to propel particles coated with DNA or cells through ascreen, such as a stainless steel or Nytex screen, onto a surfacecovered with target bean cells. The screen disperses the particles sothat they are not delivered to the recipient cells in large aggregates.It is believed that a screen intervening between the projectileapparatus and the cells to be bombarded reduces the size of projectilesaggregate and may contribute to a higher frequency of transformation byreducing the damage inflicted on the recipient cells by projectiles thatare too large.

Microprojectile bombardment techniques are widely applicable, and may beused to transform virtually any plant species. For example, Russell etal. (Plant Cell Reports, 12(3):165-169, 1993).

Agrobacterium-mediated transfer is another widely applicable system forintroducing gene loci into plant cells. An advantage of the technique isthat DNA can be introduced into whole plant tissues, thereby bypassingthe need for regeneration of an intact plant from a protoplast. ModernAgrobacterium transformation vectors are capable of replication in E.coli as well as Agrobacterium, allowing for convenient manipulations(Klee et al., Bio-Technology, 3(7):637-642, 1985). Moreover, recenttechnological advances in vectors for Agrobacterium-mediated genetransfer have improved the arrangement of genes and restriction sites inthe vectors to facilitate the construction of vectors capable ofexpressing various polypeptide coding genes. The vectors described haveconvenient multi-linker regions flanked by a promoter and apolyadenylation site for direct expression of inserted polypeptidecoding genes. Additionally, Agrobacterium containing both armed anddisarmed Ti genes can be used for transformation.

In those plant strains where Agrobacterium-mediated transformation isefficient, it is the method of choice because of the facile and definednature of the gene locus transfer. The use of Agrobacterium-mediatedplant integrating vectors to introduce DNA into plant cells is wellknown in the art (Fraley et al., Bio/Technology, 3:629-635, 1985; U.S.Pat. No. 5,563,055). Agrobacterium-mediated transformation of P.vulgaris is described in, for example, Zhang et al. (J. American Soc.Horticul. Sci., 122(3):300-305, 1997); McClean et al. (Plant Cell Tiss.Org. Cult., 24:131-138, 1991); Lewis and Bliss (J. American Soc.Horticul. Sci., 119:361-366, 1994); and Song et al. (J. Plant Physiol.,146:148-154, 1995).

Transformation of plant protoplasts also can be achieved using methodsbased on calcium phosphate precipitation, polyethylene glycol treatment,electroporation, and combinations of these treatments (see, e.g.,Potrykus et al., Mol. Gen. Genet., 199:183-188, 1985; Omirulleh et al.,Plant Mol. Biol., 21(3):415-428, 1993; Fromm et al., Nature,312:791-793, 1986; Uchimiya et al., Mol. Gen. Genet., 204:204, 1986;Marcotte et al., Nature, 335:454, 1988). Transformation of plants andexpression of foreign genetic elements is exemplified in Choi et al.(Plant Cell Rep., 13: 344-348, 1994), and Ellul et al. (Theor. Appl.Genet., 107:462-469, 2003).

A number of promoters have utility for plant gene expression for anygene of interest including but not limited to selectable markers,scoreable markers, genes for pest tolerance, disease resistance,nutritional enhancements and any other gene of agronomic interest.Examples of constitutive promoters useful for garden bean plant geneexpression include, but are not limited to, the cauliflower mosaic virus(CaMV) P-35S promoter, which confers constitutive, high-level expressionin most plant tissues (see, e.g., Odel et al., Nature, 313:810, 1985),including monocots (see, e.g., Dekeyser et al., Plant Cell, 2:591, 1990;Terada and Shimamoto, Mol. Gen. Genet., 220:389, 1990); a tandemlyduplicated version of the CaMV 35S promoter, the enhanced 35S promoter(P-e35S) the nopaline synthase promoter (An et al., Plant Physiol.,88:547, 1988), the octopine synthase promoter (Fromm et al., Plant Cell,1:977, 1989); and the figwort mosaic virus (P-FMV) promoter as describedin U.S. Pat. No. 5,378,619 and an enhanced version of the FMV promoter(P-eFMV) where the promoter sequence of P-FMV is duplicated in tandem,the cauliflower mosaic virus 19S promoter, a sugarcane bacilliform viruspromoter, a commelina yellow mottle virus promoter, and other plant DNAvirus promoters known to express in plant cells.

With an inducible promoter the rate of transcription increases inresponse to an inducing agent. Any inducible promoter can be used in theinstant invention. A variety of plant gene promoters that are regulatedin response to environmental, hormonal, chemical, and/or developmentalsignals can be used for expression of an operably linked gene in plantcells, including promoters regulated by (1) heat (Callis et al., PlantPhysiol., 88:965, 1988), (2) light (e.g., pea rbcS-3A promoter,Kuhlemeier et al., Plant Cell, 1:471, 1989; maize rbcS promoter,Schaffner and Sheen, Plant Cell, 3:997, 1991; or chlorophyll a/b-bindingprotein promoter, Simpson et al., EMBO J., 4:2723, 1985), (3) hormones,such as abscisic acid (Marcotte et al., Plant Cell, 1:969, 1989), (4)wounding (e.g., wunl, Siebertz et al., Plant Cell, 1:961, 1989); or (5)chemicals such as methyl jasmonate, salicylic acid, or Safener. It mayalso be advantageous to employ organ-specific promoters (e.g., Roshal etal., EMBO J., 6:1155, 1987; Schernthaner et al., EMBO J., 7:1249, 1988;Bustos et al., Plant Cell, 1:839, 1989). Exemplary organ-specific ororgan-preferred promoters include, but are not limited to, aroot-preferred promoter, such as that from the phaseolin gene(Sengupta-Gopalan et al., Proc. Natl. Acad. Sci. USA, 82:3320-3324,1985); a leaf-specific and light-induced promoter such as that from cabor rubisco (Simpson et al., EMBO J., 4:2723, 1985) and Timko et al.,Nature, 318:579-582, 1985); an anther-specific promoter such as thatfrom LAT52 (Twell et al., Mol. Gen. Genetics, 217:240-245, 1989); apollen-specific promoter such as that from Zm13 (Guerrero et al., Mol.Gen. Genetics, 244:161-168, 1993) or a microspore-preferred promotersuch as that from apg (Twell et al., Sex. Plant Reprod., 6:217-224,1993).

Transport of protein produced by transgenes to a subcellular compartmentsuch as the chloroplast, vacuole, peroxisome, glyoxysome, cell wall, ormitochondrion or for secretion into the apoplast, may be accomplished bymeans of operably linking the nucleotide sequence encoding a signalsequence to the 5′ and/or 3′ region of a gene encoding the protein ofinterest. Targeting sequences at the 5′ and/or 3′ end of the structuralgene may determine, during protein synthesis and processing, where theencoded protein is ultimately compartmentalized. The presence of asignal sequence directs a polypeptide to either an intracellularorganelle or subcellular compartment or for secretion to the apoplast.Many signal sequences are known in the art. See, for example Becker etal. (Plant Mol. Biol., 20:49, 1992); Knox et al. (Plant Mol. Biol.,9:3-17, 1987); Lerner et al. (Plant Physiol., 91:124-129, 1989); Fonteset al. (Plant Cell, 3:483-496, 1991); Matsuoka et al. (Proc. Natl. Acad.Sci. USA, 88:834, 1991); Gould et al. (J. Cell. Biol., 108:1657, 1989);Creissen et al. (Plant J., 2:129, 1991); Kalderon et al. (Cell,39:499-509, 1984); Steifel et al. (Plant Cell, 2:785-793, 1990).

Exemplary nucleic acids which may be introduced to the bean lines ofthis invention include, for example, DNA sequences or genes from anotherspecies, or even genes or sequences which originate with or are presentin the same species, but are incorporated into recipient cells bygenetic engineering methods rather than classical reproduction orbreeding techniques. However, the term “exogenous” is also intended torefer to genes that are not normally present in the cell beingtransformed, or perhaps simply not present in the form, structure, etc.,as found in the transforming DNA segment or gene, or genes which arenormally present and that one desires to express in a manner thatdiffers from the natural expression pattern, e.g., to over-express.Thus, the term “exogenous” gene or DNA is intended to refer to any geneor DNA segment that is introduced into a recipient cell, regardless ofwhether a similar gene may already be present in such a cell. The typeof DNA included in the exogenous DNA can include DNA which is alreadypresent in the plant cell, DNA from another plant, DNA from a differentorganism, or a DNA generated externally, such as a DNA sequencecontaining an antisense message of a gene, or a DNA sequence encoding asynthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and couldpotentially be introduced into a bean plant according to the invention.Non-limiting examples of particular genes and corresponding phenotypesone may choose to introduce into a bean plant include one or more genesfor insect tolerance, such as a Bacillus thuringiensis (B.t.) gene, pesttolerance such as genes for fungal disease control, herbicide tolerancesuch as genes conferring glyphosate tolerance, and genes for qualityimprovements such as yield, nutritional enhancements, environmental orstress tolerances, or any desirable changes in plant physiology, growth,development, morphology or plant product(s). For example, structuralgenes would include any gene that confers insect tolerance including butnot limited to a Bacillus insect control protein gene as described in WO99/31248, herein incorporated by reference in its entirety, U.S. Pat.No. 5,689,052, herein incorporated by reference in its entirety, U.S.Pat. Nos. 5,500,365 and 5,880,275, herein incorporated by reference ittheir entirety. In another embodiment, the structural gene can confertolerance to the herbicide glyphosate as conferred by genes including,but not limited to Agrobacterium strain CP4 glyphosate resistant EPSPSgene (aroA:CP4) as described in U.S. Pat. No. 5,633,435, hereinincorporated by reference in its entirety, or glyphosate oxidoreductasegene (GOX) as described in U.S. Pat. No. 5,463,175, herein incorporatedby reference in its entirety.

Alternatively, the DNA coding sequences can affect these phenotypes byencoding a non-translatable RNA molecule that causes the targetedinhibition of expression of an endogenous gene, for example viaantisense- or cosuppression-mediated mechanisms (see, for example, Birdet al., Biotech. Gen. Engin. Rev., 9:207, 1991). The RNA could also be acatalytic RNA molecule (i.e., a ribozyme) engineered to cleave a desiredendogenous mRNA product (see for example, Gibson and Shillito, Mol.Biotech., 7:125, 1997). Thus, any gene which produces a protein or mRNAwhich expresses a phenotype or morphology change of interest is usefulfor the practice of the present invention.
